Thanks, last one about multiple datums frames was a great example! I also got a question about where you talked about the pattern and how we need to use the position instead of perpendicularity for datum B, which makes sense. However how do we tell manufacturer the actual position of the pattern itself (the relative location of holes in the pattern is clear and identified, but how do we specify how much the pattern should be up and down, and do we need another DRF to make that clear to machinist?) Kind of similar question to this is figure 4.9 of 2009 standard, it's not clear where datum B is, again relative positions are specified, but how does machinist know where to drill hole B to begin with, they only know it should be perpendicular to A. Thanks, and sorry for very long question 😅

Hi, great question! The short answer is to think of all the of the features being relative to the pattern of holes serving as a datum. Often this is a profile with a wide tolerance for areas that mate to air. Does this help?

I'm a bit confused. In a different datum video, you said we can't use flatness as a datum feature of size, but in this one, it is shown as an example for the middle depiction. Am I misinterpeting something? Or is there a rule that allows it?
@RDeanOdell
Жыл бұрын
Hi, it the other video I was showing ways to apply datum feature symbols to indicate the datum is a surface. A flatness applied to a DMP can be used as a datum, but it is not common. It is not ideal as a primary datum, it is difficult to simulate.

Can you make a video over the terminology of which datums control what? For example, if a profile can control location, size, form, and orientation, and a call out has three datums, does the primary datum control the location and orientation, the secondary controls form, and what does the tertiary control? Or if it only had two datums called out, what does it mean to the machinist or manufacturer as to what is "more important" to the designer? Form and orientation and disregard location and size?

Thanks for your clear explanation. I think datum reference frame is the most important chapter in GD&T. I have a question about setting hole pattern as datum. As you mentioned, the measurement origin is the center of those four holes. How can I determine the orientation of this Datum Reference Frame on CMM? Can I choose any one of these holes for alignment?

Is GD&T required for CAD product design? At what stage of product design would GD&T be most useful?
@RDeanOdell
Жыл бұрын
Hi, it’s not required. Some companies don’t use it at all. The thing is, the companies that do use it make it very important. It is used during the early design process in modeling parts, then in the drawing phase to document the design intent.
@learnthrivecompassion422

The drawing phase is not preceeded by the modeling parts phase? And by modeling parts, are you referring to creating them in a CAD program typically?

Suggested topic from my side for your future videos...Let us say I have a rectangular part with a large 45 deg chamfer on one edge through which a hole is drilled. If that 45 deg(45 deg to horizontal) surface becomes my primary datum for the hole then how will my cartesian co-ordinates change & how will the basic dimension be used to locate the hole etc. Please amuse me by answering this Q.
@shankar554
2 жыл бұрын
Please do not ask me to put basic angle B/W axis of datum & the horizontal plane & provide angular geometric tolerance. I want to make sure that the chamfered surface is my primary datum for the hole so that I can ensure that hole is perpendicular to this surface.

Hi, I would make that chamfer surface the primary datum for whatever features exist there. So you would need more than one DRF. I’ll see what I can do about a video covering multiple DRFs.
